“Turning to the substantive issues, we find the District Court’s “mirror tracking mode” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning. As the District Court points out, both the “double the distance” and “same size” aspects of its construction are expressly discussed in the ’109 patent, which is incorporated in the ’110 patent. See Ex. 2008, 16 (citing Ex. 1021, 2:5–27, Figs. 5A, 5B), 40 (citing “same reasons set forth regarding the term ‘it appears to mimic a reflection of a mirror’” in support of construction of “mirror tracking mode”).

“Post-institution, Patent Owner invites us to construe limitation 1[f]’s recitation of “mirror tracking mode” and limitation 1[c]’s recitation of “adaptive transformation mapping.” PO Resp. 9–14. Regarding the latter, Patent Owner explains that “[i]n the District Court Litigation, ‘adaptive transformation mapping’ was construed as ‘continuously variable transformation mapping’ and ‘transformation mapping’ was construed as a ‘selected set of image transformations.’” Id. at 14 (citing Ex. 2008, 14, 37; Ex. 2013 ¶¶ 25, 27). Patent Owner does not, however, identify any way that those claim constructions affect our analysis of the parties’ patentability disputes. We find it unnecessary in resolving the parties’ patentability disputes to construe expressly limitation 1[c]’s recitation of “adaptive transformation mapping.”” slip op. at 11

“persuasively address limitation 1[f]’s “mirror tracking mode.” In particular, Petitioner does not address persuasively the requirement, as explained in Section II.B above, that mirror tracking mode involves processing camera-captured images in a way that “maintains roughly the same size regardless of the user movement.” At odds with this requirement, Petitioner founds its case on an assertion that “Haan teaches the claimed mirror tracking mode” because “if the viewer is within 35 cm of the camera, a tracking mode is entered, applying resizing transformation.” Pet. 44 (emphasis added) (citing Ex. 1005 ¶¶ 75–76, 80–82, 90–94, 97; Ex. 1003 ¶¶ 205–210). The resizing transformation Petitioner references actually involves magnifying the user’s image by an amount that changes based on the user’s position relative to the camera, quite the opposite of maintaining image size regardless of the user movement. Ex. 1005 ¶¶ 75–76, Fig. 8. Thus, Petitioner’s initial position is unpersuasive. Petitioner’s shift to Haan’s “reflective mirror mode and conventional mirror period in the dual mode” is also unavailing. Reply 8. Consistent with Patent Owner’s arguments, Petitioner does not provide persuasive evidence that these operating states of Haan’s device involve any processing of camera-captured images. Sur-reply 13–14. To the contrary, Haan suggests that anytime its device provides an unmagnified image, it comes from a reflection off a physical reflective surface. See, e.g., Ex.1005 ¶ 76 (“This can be done for instance by using the device as a simple mirror, i.e. not displaying an image on the display device, but using the device in the reflective mode.”) (emphasis added), ¶ 92 (“a simple reflective mode, to act as a mirror”), ¶ 29 (“for a first range of positions, no image is displayed, whereby the reflective layer acts as a mirror, and for a second range of positions, the recorded image is displayed.”) (emphasis added). We also find unpersuasive Petitioner’s Reply arguments based on Haan’s disclosure of smoothly transitioning from “using the device as a simple mirror” (i.e., using a physical reflecting surface) to displaying a magnified image. Reply 11 (citing Ex. 1005 ¶¶ 76, 80). To the extent this may establish a point around the transition at which Haan’s system displays an image with relatively little magnification, it does not establish that Haan teaches, suggests, or renders obvious holding the displayed size roughly constant, “regardless of the user movement.” Indeed, given Haan’s focus on helping the user see things more clearly with image magnification, Petitioner’s argument that it would have been obvious to hold the size of the image constant is not persuasive. See, e.g., Ex. 1005 ¶ 4.” slip op. at 23

“Putting aside the controversy over alleged impropriety and sandbagging in connection with the District Court’s Order, which we address infra in connection with Patent Owner’s Motion to Strike, we find the District Court’s “mirror-mimicking” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning.

We, however, disagree with Petitioner that we should not construe this term.

A reference may be said to “teach away” “when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” Galderma Lab'ys, L.P. v.

“We find that Petitioner has not demonstrated by a preponderance of evidence that step 1(h) is taught or suggested by the references cited by Petitioner or the testimony of Petitioner’s expert, Dr. Karam. We agree, instead, with Patent Owner’s argument that “a [person of ordinary skill] would regard the disclosures in Rosenberg relating to proximity detection to be in connection with turning on or off various display modes and not in connection with varying the rate of one or more steps that are performed to transform a series of captured images of a user.” PO Resp. 33 (citing Ex.1005, ¶¶ 25, 32, 56, 69, 114). This distinction was explored during the final hearing. Petitioner’s counsel confirmed that in Rosenberg’s mirror mode, the rate of performing the processing steps does not vary: [THE BOARD]: It’s true that when the -- when Rosenberg is acting in the mirror mode, it’s always at the same rate, correct? It’s always performing those three processing steps at the same rate? [COUNSEL]: Correct. Hearing Tr. 34:13–16. We conclude that Rosenberg fails to disclose or suggest step 1(h) for the reasons given by Patent Owner and summarized above.

Indeed, in Unified Patents, LLC v.

Here, as neither the Chinese government nor YMTC Holding have been sued for patent infringement, Patent Owner has not shown that a determination of whether the Chinese government or YMTC Holding are an RPI, or are in privity with Petitioner, would impact the underlying proceeding or result in a time bar or estoppel. As such, we do not address Patent Owner’s RPI argument. We have also considered Patent Owner’s contention that the Chinese government may file additional IPR proceedings through other Chinese semiconductor companies, such as Fujian Jinhua Integrated Circuit Co., Ltd., if this petition is denied or unsuccessful and that real party in interest provisions seek to protect patent owners from harassment via “successive petitions by the same or related parties.” Prelim. Resp. 25; see also Unified Patents¸ Paper 76 at 5 (noting Petitioner’s argument that a non-binding advisory opinion on RPI would prejudice the asserted RPI parties by prejudging the issue without their participation). Concerns that future petitions may be filed by parties that are the same or related to Petitioner may be addressed in any such future proceeding. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019)9 (“Consolidated TPG”), 55–63; General Plastic Co., Ltd. v. Canon Kabushiki Kaisha, IPR2016-01357, Paper 19 at 15–18 (PTAB Sept. 6, 2017) (precedential) (recognizing the “potential for abuse of the review process by repeated attacks on patents” and setting forth factors to consider in exercising discretion on instituting inter partes review as to “follow-on” petitions challenging the same patent previously challenged in an inter partes review proceeding). As such, we do not deny institution for Petitioner’s alleged failure to list all RPIs.” slip op. at 19

“Petitioner’s own formulations of the grounds based on either Seo or Nam in combination with Choi posit the alternative theories that either Seo or Nam alone disclose Limitation [1.D], or the combination of either Seo or Nam with Choi teaches this limitation. Although Petitioner did not invoke inherency by name for the theories based on Seo or Nam alone, this is, in effect, the nature of Petitioner’s assertions, namely, voltage differentials in Seo and Nam would inherently remove fast charges. For example, with respect to Seo, Petitioner argues that “Seo teaches having a higher voltage on unselected WLs (e.g., adjacent WLs to the selected WL) during the first time period,” and “the ’342 patent recognizes [that] this voltage differential removes fast charges.” Pet. 35–36 (citing Ex. 1001, 12:24–34; Ex. 1003 ¶¶ 129–131) (emphasis omitted); see also id. at 82–83 (relying on the ’342 patent to support the contention that Nam teaches Limitation [1.D] because Nam “teaches having a higher voltage on unselected WLs (including WLs adjacent to the selected WL) relative to the selected WL during the first time period” (citing Ex. 1001, 12:24–34) (emphasis omitted)). Petitioner does not argue that Seo and Nam expressly disclose removing fast charges or sufficiently explain how a POSITA would have understood that the procedures used in Seo and Nam would have removed fast charges; instead, Petitioner effectively argues that removing fast charges is the inherent result of applying the voltage differential. See, e.g., Pet. 36 (stating Seo would have been understood to disclose “performing its read operation on chargetrap memories, which removes fast charges”).” slip op. at 5

“Petitioner’s reliance on Choi does not cure the deficiencies set forth above. Petitioner asserts that “Choi explains the primary mechanism and unwanted impact of fast-charge loss on verification,” which provides the motivation “to use Seo’s and Nam’s methods to achieve fast charge removal to improve verification.” Req. 7 n.1. But again, Petitioner does not sufficiently explain how a POSITA, looking at Choi, would have understood that either Seo’s or Nam’s techniques result in fast charge removal. In other words, even if Choi teaches the impact of fast-charge loss on verification, Petitioner fails to sufficiently show that a POSITA would have understood that either Seo or Nam teach or suggest fast charge removal. It was Petitioner’s burden to establish that Seo and Nam, alone or in combination with Choi, disclose Limitation [1.D].
